実験手順

1.46 g (4.5 mmol) of 5-(5-fluoro-2-methoxyphenyl)-5-methyl-3-(trifluoromethyl)hexane-2,3-diol and 3.14 ml (22.5 mmol) of triethylamine in 16.3 ml of DMSO and 50 ml of methylene chloride are mixed in portions with 4.3 g (27 mmol) of pyridine-sulfur trioxide complex at room temperature. After 20 hours at room temperature, it is hydrolyzed with saturated ammonium chloride solution while being cooled with ice and extracted with diethyl ether. The combined extracts are dried (sodium sulfate) and concentrated by evaporation. Column chromatography on silica gel with hexane-ethyl acetate yields 1.04 g of the product.
